When you need help picking out a new book, gadget, hairstylist, or even doctor, what do you do?

Turn to online reviews, of course! Almost all online retailers, from Amazon to individual retail e-boutiques, provide a way for customers to review their products and services. And we, as consumers, scour these reviews to guarantee we’re making the perfect choice.

So it should be no surprise that there are company review sites, like Glassdoor.com and Jobitorial.com, that provide a window-shopping experience for the modern jobseeker. You can see reviews and information (like average salaries) from current and former employees—all designed to help you gauge the overall company experience.
